JAMES F. OSHAUGHNESSY, OF NElV YORK, N. Y., ASSIGNOR TO THE UNITED STATES COTTON SEED COMPANY, OF SAME PLACE.

METHOD OF TREATING COTTON-SEED.

SPECIFICATION forming part of Letters Patent No. 298,617, dated May 13, 1884,

Application filed October 13, 189:3. (No specimens.)

To all whom it may concern.-

Be it known that 1', JAMES F. OSHAUGH- NEssY, of New York, in the county of New York and State of New York, have invented 5 a new and useful Method of Treating Cotton Seed; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to an improved method of treating cotton-seed for the purpose of ob taining its products at less expense in better condition.

Heretofore, as is well known, cotton-seed has been crushed with the hull and kernel together, and the oil expressed. lhis process requires that the hull, which contains no oil whatever, shall be subjected to the same amount of compression as the kernel itself, which alone contains the oil. The food product, which has the mixed hull and kernel, is in good condition for its purpose; but the oil is rendered darker by reason of the presence of the hull in the compressed mixture.

It has also been common to hull the Ameri;

can upland seed and crush only the kernel, and to burn the hull with the adherin lint as fuel. This avoids the discolomio 0f the oil caused by pressing the hall; but the food product-that is to say, the pure kernel is lack- 0 ing in an element required to make it a proper food i'oreattlc to be fed by itself that is to 13, it lacks the hull, which, when ground with "the kernel, makes a better and more whole some food.

5 Myinvention therefore consists in the meth- 0d of treating cotton-seed by taking the hull separated from the kernel and grinding it, in removing the fiber therefrom, and then mix ing the ground hull with the crushed and pressed kernel, as hereinafter more particu- 4o larly described and claimed.

I grind the hull separately, and when it contains fiber I separate the fiber therefrom in the manner described in Letters Patent No. 286,553, granted me on the 9th day of Octoher, 1883. I After thus grinding the hull and separating the fiber, which is unfit for food, but is valuable for other purposes, I mix the ground hull with the kernel from which the oil has been expressed, and form therefrom the food product. I thus obtain the fiber, the food product in its best form, and the oil in its best condition, and without any of the dis coloration arising from the compression with the hull.

The Various steps in the operation a b carried on by well-known a ga -Titus, any suitable mill being uscQ/fof grinding the hull, a y Ordinary pines for pressing the kernel, 11nd the fiber may be removed from the ground 6o lljyauy suitable winnowing or sitting apparatus.

I claim' The herein-described method of treating cotton-seed, consisting in taking the hull sepa rated from the kernel and grinding it, in removing the fiber therefrom, and then mixing the ground hull with the crushed and pressed kernel, all substantially as described.

In testimony whereof I havesigned my name to this specification in the presence of two subscribing witnesses.

JAMES F. OSHAUGHNESSY.
